Ever smoke a “hash hole”? If you’re a first timer, fair warning: You probably won’t be prepared for the aftermath of the hit.

Imagine taking a dab and ripping a bong at the same time, conveniently rolled up into a single joint. The potency, convenience and taste is why they’re one of the hottest trends in the cannabis community.

Hash holes quite literally incorporate a sliver of hashish placed in the middle of a pre-roll. The hand-rolled extracts begin in a worm shape, effectively increasing potency while mixing exceptional flavor into the flower. Solventless rosin with big terpy flavors are most recommended.

Once the joint starts burning, it eventually creates a hole in the middle of the roll as the hash disappears into the flower. Looking from the bottom up, it looks like a donut, which is why these have also been nicknamed donut holes (along with snake holes and wormholes).
